This UAG's aim is to extract atmospheric thermal energy and use it to supplement its battery energy usage and increase the mission period. Given an identified atmospheric thermal of known strength and location; current wind speed and direction; battery level; altitude and location of the UAG; and estimating the expected altitude gain from the thermal, is it possible to make an energy-efficient based motivation to fly to an atmospheric thermal so as to achieve UAG extended flight time? For this work it is assumed that candidate atmospheric thermal locations are of known longitude/latitude location, size, and strength. An algorithm, based on a fuzzy logic approach, is then developed to incorporate all available information with the current UAG status to provide an energy-based recommendation to modify the flight path from the nominal mission trajectory. Research, development, and simulation of the decision-making algorithm is the primary focus of this work. Three models are developed: Battery Usage Model (BUM), Altitude Gain Model (AGM), and Intelligent Decision Model (IDM).","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127772289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting thermal-fluid flow patterns from such systems tend to be sensitive to disturbances, and advanced flow control techniques are important to maintain occupant comfort. In this work, we employ Eigensystems Realization Algorithm (ERA) to obtain low-order models of airflow in buildings, which capture relevant dynamics and are amenable for control design. We present an alternative interpretation that allows one to obtain models using ERA, without resorting to lifting, an approach that is typically used to introduce boundary control and boundary disturbances explicitly in the reduced-order model. Using this reduced-order model we derive an optimal control law in closed form (which is composed of a feedforward and a feedback term) for rejecting a known disturbance, while minimizing a quadratic cost related to occupant discomfort and energy consumption. We demonstrate this approach using closed loop CFD simulations of airflow in a room with a passively cooled radiant ceiling and a displacement vent.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131360080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Piezoelectric cantilevers, used as microactuators in micromanipulation and microassembly con texts, are particularly concerned. Due to their small sizes, these systems are very sensitive to environment (temperature, vibration, etc.) and to usury during functioning. Their behaviors often change because of the parameters variation. For that, linear modeling with uncertainty has been used to account the uncertainties, then classical H∞ and μ-synthesis approaches were applied. These techniques were efficiency but they were of high order which is not suitable for embedded microsystems. Furthermore, when the number of uncertain parameters increases, the modeling of microsystems became delicate and difficult. In this paper, we propose to model the uncertain parameters by bounding them with intervals. After wards, we propose to design a robust PID controller by using interval arithmetic and related tools in order to ensure the specified performances. In addition to the simplicity of the uncertainties modeling, the derived controller is of low order. The controller synthesis is formulated as a set-inversion problem. An application to the control of piezoelectric microactuators proves the efficiency of the proposed method.","PeriodicalId":225201,"journal":{"name":"Proceedings of the 2011 American Control Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131396202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
